Advice 1: How to convert Newtons to Pascals

Newton – unit of force, and Pascal – unit of pressure. And people who are not well versed in physics, it often seems that the task to translate Newtons to Pascals is as absurd as the translation of grams per ampere. And, indeed, the literal translation of the question. You only need to conduct simple calculations in accordance with the existing formula.
How to convert Newtons to Pascals
You will need
  • calculator
Recall that by definition, the Newton (N, N) is equal to the force gives the body a mass of 1 kg acceleration of 1 m/s^2 in the direction of action of the force. If the strength in Newtons obtained by you as a result of calculations in the course of solving the problem, re-calculate everything again, check yourself. Make sure that you have made the preliminary calculations are correct and you are absolutely precisely calculated force in Newtons. Next, recall that Pascal (Pa)equal to the pressure which causes a force equal to one Newton uniformly distributed on a surface area of 1〖 m〗^2 that is perpendicular to this force. That is, by definition: 1 PA=N/m^2.
Calculate the surface area, which is under pressure in accordance with the terms of the tasks set before you. To compute the area apply the appropriate mathematical formula. Please note that the area must be measured in square metres and not in any more units. If necessary, make a translation of your existing units of area measurement in square meters. Divide previously received by you in Newtons force on the area in square meters. For calculations, use a calculator. The result of the division is required you pressure is indicated in Pascals. Write down the result. The problem is solved.
Call a classmate, a classmate or a friend who knows physics (assuming that all that is written above does not help you). Tell him about your problem. Politely ask him to stop laughing and to dictate a solution to this problem is up to each numbers and letters, or to send an SMS, MMS or email. If the request was denied, or among your acquaintances there is no one versed in physics, the person will ask for help to the users of the Internet. Surely among the inhabitants of any theme of the forum will find at least one helpful person, who will write you a detailed solution to your problem absolutely free. Thank this man and rewrite the solution.
Re-read textbooks on physics and still try to understand at least part of what is written there. If necessary, seek clarification from the teacher. The obtained knowledge will be useful to you in your life again and again.

Advice 2 : How to convert from millimeters of mercury to Pascals

The millimeters of mercury and Pascals used to measure pressure. Although Pascal is the official system unit non-si millimeters of mercury according to its frequency were not inferior to them. "Millimeters" even have their own name – "Torr" (torr), given in honor of the famous scientist Torricelli. Between the two units there is an exact relationship: 1 mm Hg. article = 101325 / 760 PA, which is the definition of the unit "mm Hg. article".
How to convert from millimeters of mercury to Pascals
You will need
  • calculator;
  • computer;
  • - the Internet.
To convert a pressure given in millimeters of mercury, Pascals, multiply the number of mm Hg. article on the number of 101325, and then divide by 760. That is, use a simple formula:

KP = Km * 101325 / 760,

Km – pressure in millimeters of mercury (mm Hg. art., mm Hg, Torr., torr)
KP is the pressure in Pascals (PA, RA).
The use of the above formula gives the exact correspondence between the two measurement systems. For practical calculations use a simple formula:

KP = Km * 133,322 or simplistic KP = Km * 133.
When the pressure in Pascal note that when measuring blood pressure in weather reports, as well as among engineers vacuumseal often shorten the name of "mm Hg. article" to "mm" (sometimes omitted and millimeters). Therefore, if the pressure is given in millimeters or just a number is specified, then it's probably mm Hg. the article (if possible, still more precise). When measuring very low pressure is mm Hg. the article "vacuumsthe" apply unit "microns of mercury", which is commonly referred to as "microns". Accordingly, if the pressure is specified in microns, then simply divide that number by a thousand and get the pressure in mm Hg. article
When measuring high pressures often used such a unit as "atmosphere", corresponding to normal atmospheric pressure. One atmosphere (ATM, atm) equals 760 mm Hg. article that is, for obtaining the pressure in mm Hg. article, multiply the number of atmospheres to 760. If the pressure is specified in "technical atmospheres", to translate pressure in mm Hg. St. multiply this number by 735,56.
The tire pressure of the car is 5 atmospheres. What will be the pressure expressed in Pascals?

Move pressure from atmospheres to mm Hg. article: 5 * 760 = 3800.
Put the pressure of mm Hg. article in the Pascal: 3800 * 133 = 505400.

505400 PA (or $ 505.4 bn kPa).
If you have a computer or a mobile phone with access to the Internet, just look for any online service convert physical units of measure. To do this, type in a search engine a phrase such as "translate from mmHg to Pascal" and use the instructions on the service website.
